dav-mcp

Overview

dav-mcp is a comprehensive MCP server that transforms AI agents into organizational assistants capable of managing calendars, contacts, and tasks through CalDAV, CardDAV, and VTODO protocols. It offers 26 production-ready tools, significantly more than typical MCP servers which usually provide only 2-6 tools. The server supports full CRUD operations, field-based updates, server-side filtering, and works across multiple providers including Nextcloud, iCloud, and any RFC-compliant server. It can be used both locally with Claude Desktop or Cursor and remotely via HTTP in n8n workflows.
